Purpose - This research investigates the old marketing mix approach to satisfaction and loyalty from the perspective of research subjects of Samsung brand smartphone cases through empirical testing involving product quality, price, distribution channel variables as antecedent variables. Research design, data, and methodology - This study emphasizes the empirical/quantitative concept by using a survey as a data collection tool. The number of samples used was 179 eligible respondents who used Samsung smartphone devices for more than five years. Statistical testing tools use PLS with several testing stages such as the classical assumption test to the hypothesis testing stage. Results - The nine hypotheses proposed, as many as two hypotheses were proposed, namely intervening relationships involving Price and Distribution channel variables on customer satisfaction and customer loyalty. Conclusions - Product quality is the essential component affecting customer satisfaction and loyalty while distribution channel is a complementary component that is no less important to measure the extent to which customer satisfaction expectations and customer loyalty are realized for the product quality of the products that have been produced and marketed. The price component is not the only reason to make consumers satisfied and loyal.

In the case of Ni/Au finished pad on the package side, the solder joint of SnAgCu system can bring brittle fracture under impact load such as drop test. Therefore, it's difficult to prevent the brittle fracture of lead-free solder, by controlling Cu content. The failure locus existing on the interface between $(Ni,Cu)_3Sn_4\;and\;(Cu,Ni)_6Sn_5$ IMC layers must be changed to other site in order to avoid brittle fracture due to impact load. It was not found any clear evidence that there were two IMC layers exist. But it was strongly assumed these were two layers which have different Cu-Ni composition. From the above analysis it was assumed that Cu atom in the solder alloy or substrate seemed to affect IMC composition and cause to IMC brittle fracture.

New concept of energy recovery for plasma display panel (PDP) Is proposed. Different from conventional LC resonant sustaining drivers, the current built up before inverting the polarity of the panel electrodes is utilized to change the panel Polarity together with energy Previously charged in Panel capacitance. This operation Provides zero -voltage-switching of switches and reduction of EMI by rejecting the surge current when the sustain switches are turned on. The build-up current helps to reduce transition time of panel polarity and may produce more stable light waveforms. This method shows a desirable characteristic that the circuit loss is similar to that of series resonant type energy recovery circuit which is very effective method.

The objective of this research is to analyze the product innovation aspect in two comparable smartphones and partly illustrate perception and preference of Vietnamese consumers of two smartphone lines of Apple - iPhone 6 Plus and Samsung - Samsung Galaxy Note 4. The research tries to clarify which innovative features in two smartphones are more preferable to a group of consumer in Vietnam. The reason why the research studies iPhone 6 Plus and Samsung Galaxy Note 4 when iPhone 7 and Samsung Galaxy Note 7 have just released is that passing more than one year is enough time for consumers to totally experience both 2 smartphone lines to give the most precise and truthful evaluation for their preferences. Moreover, iPhone 6 Plus launch signed one of the most historical memorable landmark in the development process of iPhone products when it introduced larger-screen iPhone model for the first time. It is such an important change of iPhone which could open a new continuing successful era for Apple and iPhone. The first phase of this study involves analyzing strengths and weaknesses existed considering the opportunities and threats from the competitive market, then a competitive advantage analysis is implemented for each product. The second phase conducts a survey with Vietnamese participants from different backgrounds, by which a Mann-Whitney U test will be executed to check the significant difference in opinions in different respondent groups by age and by gender to several features of two smartphones. By conducting the survey, some interesting facts revealed with the winner seemingly falling into iPhone 6 Plus. However, it still reveals some significant difference among respondent groups by age and by gender to both iPhone 6 Plus and Samsung Galaxy Note 4 in several comparing features.

The metal lead frame, a semiconductor component, has product tolerances in micro units as compared to products made with a larger size mold. Therefore, small deflections of the mold and of the press as well as the press molding process itself have a strong influence on accuracy of the product. Hence, it is necessary for the process design to consider the structural response of the mold and the press during deformation. In the current study, the mold deflection and pressure on the punch is examined using the finite element modeling (FEM) program ABAQUS. The results from the simulation were verified with the dynamic deformation measurement equipment using digital image correlation (DIC).

This paper presents a high-speed pulse-based flip-flop with pseudo MUX-type scan compatible with the conventional master-slave flip-flop with MUX-type scan. The proposed flip-flop was implemented as the standard cell library using Samsung 130nm HS technology. The data-to-output delay and power-delay-product of the proposed flip-flop are reduced by up to 59% and 49%, respectively. By using this flop-flop, ARM11 softcore has achieved the maximum 1GHz operating speed.

Purpose: For improving outgoing quality, this study presents a novel sampling framework based on predictive analytics. Methods: The proposed framework is composed of three steps. The first step is the variable selection. The knowledge-based and data-driven approaches are employed to select important variables. The second step is the model learning. In this step, we consider the supervised classification methods, the anomaly detection methods, and the rule-based methods. The applying model is the third step. This step includes the all processes to be enabled on real-time prediction. Each prediction model classifies a product as a target sample or random sample. Thereafter intensive quality inspections are executed on the specified target samples. Results: The inspection data of three Samsung products (mobile, TV, refrigerator) are used to check functional defects in the product by utilizing the proposed method. The results demonstrate that using target sampling is more effective and efficient than random sampling. Conclusion: The results of this paper show that the proposed method can efficiently detect products that have the possibilities of user's defect in the lot. Additionally our study can guide practitioners on how to easily detect defective products using stratified sampling

The effect of the scan velocity modulation is studied. The effect of the velocity modulation on the picture image is judged from the intensity profile of the image. The intensity profile is obtained as time integral of moving Gaussian beam. To confirm the applicability of this integral formula, the measurement and simulation data is compared. And by calculating the intensity profile for different amounts of velocity modulation, the optimum modulation displacement that gives the best image quality is obtained. This optimum modulation displacement can be used in designing scan velocity modulation system.
